3. Pick 3 stimuli and rank them in order of CS effectiveness according to Rescorla/contingency theory. Explain why Rescorla ranks them in this order. (Note they don't all need to be good CS+.)

4. Pick one stimulus that Pavlov would expect to be a good CS+ but Rescorla might not. Why the difference?

5. What is the UCR according to Pavlov and Siegel?
